摘　　要：针对传统的单Sink节点无线传感器网络应用于煤矿安全监控系统中时,远离巷道口的传感器节点无法及时、准确地将巷道深处的监测数据传输到巷道口Sink节点的问题,提出一种适用于长带状结构煤矿巷道的基于多Sink节点的无线传感器网络路由协议。该协议引入多Sink节点的无线传感器网络结构和非均匀成簇的思想,采用基于多Sink节点的功率控制算法和非均匀成簇算法,对各个Sink节点的最优通信半径、发射功率、簇首的选择和非均匀竞争半径的计算进行优化。仿真结果表明,该路由协议在连通度、延时和网络生存期上具有优势,可有效降低无线传感器网络整体能耗,延长网络生存期。When traditional wireless sensor network based on single sink node is applied in coal mine monitoring system,the sensors far away from tunnel crossing cannot transmit monitoring data to sink nodes in the tunnel crossing real timely and exactly.In order to solve above problem,a routing protocol for wireless sensor network based on multi sink nodes was proposed which was suitable for long strip structure of coal mine tunnel.The protocol introduces wireless sensor network structure based on multi sink nodes and unequal clustering thought,and adopts a power control algorithm based on multi sink nodes and an unequal clustering algorithm to optimize the optimal communication radius,transmit power,cluster head selection and calculation method of unequal radius of each sink node.The simulation results show that the protocol has advantages in connectivity,delay and network lifetime,and can reduce the whole network energy consumption effectively and prolong network survival time.
